Session 110 | Geneva | 25-29 Apr 2016
12. Regulation No. 110 (Specific components for CNG)
GRSG/2016/6 | Proposal for amendments to Regulation No. 110 Proposal to harmonize UN R110 with standard ISO 11439:2013 on high pressure cylinders for the on-board storage of natural gas as a fuel for automotive vehicles.
GRSG/2016/8 | Proposal for amendments to Regulation No. 110 Proposal to allow the use of Class 0 hoses with couplings using sealing technologies other than those with a 45° cone. Currently, non-seamless double and single wall tubes are used in brake and fuel tubing applications, allowing for the use of a variety of end forms and coupling techniques. Provided the hose assembly can withstand the impulse test of paragraph 1.7. and the tests of Annexes 5A (overpressure test) and 5B (external leakage test), such configurations should be permitted under UN R67 in order to remove an unwarranted design restriction. In cases where a soft seal body (e.g. O-ring) is used, the compatibility of the material with use conditions must be demonstrated by testing according to Annexes 5D (CNG/LNG compatibility test), Annex 5F (resistance to dry heat) and Annex 5G (ozone aging).
GRSG/2016/9 | Proposal for amendments to Regulation No. 110 Proposal to correct a typographical error in paragraph 7.1. where the reference should be to paragraph 8.22 rather than 8.21, to remove a duplicate and contradictory reference in Annex 4A to the requirements of Class 1 pressure relief valves, and to align paragraph 2.2. of Annex 4H with paragraph 18.6.1.2. limiting the delay in switching-off of the automatic valve after stalling of the engine to two seconds (rather than five as presently in the text).
GRSG/2016/10 | Proposal for amendments to Regulation No. 110 Proposal to include the liquefied natural gas (LNG) fuel connector provisions as specified in ISO 12617:2015.
GRSG-110-05 | Proposal for amendments to Regulation No. 110 Proposal to align the CNG cylinder requirements in Regulation No. 110 with requirements in ISO 11439: 2013.
GRSG-110-23 | Proposal for amendments to Regulation No. 110 Proposal to allow for the use of natural gas refrigeration systems to vehicles propelled by natural gas (CNG or LNG). This proposal addresses a new, environmentally friendly natural gas fuelled refrigeration system for trucks with refrigerated loads that already are propelled by natural gas. Currently paragraph 18.1.7.1 allows heating systems to be fitted on vehicles to heat the passenger compartment and/or the load area of a vehicle, however, the same provision omits cooling systems that are used on trucks for the carriage of loads requiring refrigeration.
GRSG-110-26 | Proposal for amendments to Regulation No. 110 Editorial amendment to document GRSG/2016/8 for clarity. The original proposal would allow the use of Class 0 hoses with couplings using sealing technologies other than those with a 45° cone provided that the hose assembly can withstand the impulse test of paragraph 1.7. and the tests of Annexes 5A (overpressure test) and 5B (external leakage test). This proposal clarifies that the original sealing-cone specification or other compliant couplings, including designs with soft seals (e.g., O-ring) provided they pass testing described in Annexes 5D, 5F, and 5G.
GRSG-110-27 | Proposal for amendments to Regulation No. 110 Proposal to amend GRSG/2015/36 introducing requirements for the operation of a CNG heater when the vehicle is stationary and before starting the engine. The limitation on the number of valves used to operate the CNG combustion heater will require technical changes without any significant benefit. The proposal therefore deletes the limitation and introduces additional clarifications.
GRSG/2015/36 | Proposal for amendments to Regulation No. 110 Proposal to enable the use of autonomous CNG heaters for the heating of engines before the vehicle is in service.
